SPINNING-RING.

Bpecloation of Letters Patent.

Patented Nov. 23, 1915.

Application med November 80, 1914. SerialNo. 874,707.

To all whom it may concern Be it known that I, JOHN. V. CUNNIFF, a citizen of the United States, and a resident of Fall River, in the county of Bristol and State of Massachusetts, have invented an Improvement in Spinning-Rings, of which the following description, in connectionwith the accompanying drawings, is a speclfication, like characters on the drawings representing like arts.

rlhis 1nvent1on relates to spinning rings and particularly to stationarily mounted spinning rin s.

In order t at the principle of the invention ma be readily understood, I have representedy a single embodiment thereof in the accompanying drawing, wherein- Figure 1 is a vertical, central sectlon, on an enlarged scale, of a. spinning ring embodying my invention; and Fig. 2 is a plan View thereof.

An important purpose of my invention 1s to provide a spinning ring of such construction as to result in a material reduct1on 1n the friction of the traveler thereon.

A further important object is to provide a i spinning ring of such construction that the traveler can be more readily ap lied thereto, and without straining the trave er, thus materially reducing the life thereof.

A still further object is to enable the use of heavier travelers than heretofore, in spinning the various counts of yarn. c

Iurther objects of the invention w1ll be set forth hereinafter.

Referring more particularly to the drawings, the spinning ring is indicated enerally at 1. While the ring is preferab y st ationarily mounted upon the rlng frame 1n any usual manner, it may be of the so-called rotary type. I have herein represented it as having a lower or basal Harige 2 wh1ch may be ofany suitable construction not hereln necessary more fully to set forth. The upper or traveler flan e or race of the ring 1s indicated at 3. It 1s preferably of slightly less width than heretofore. At its mner edge it may be of usual or desired vertical thickness or extent. From a point at or, if desired, close to the inner edge 4 of the traveler flange, the top of the said flange slopes downwardly and outwardly to a substantially thin edge 5 as clearly re resented in Fig. 1. The said thinouter e ge presents lcontact to the traveler. Within the scope of my invention the angle or degree of slope may be varied, but I have obtained excellent results when employing substantially the slope indicated, which is gradual.

In the disclosed embodiment of applicants invention, the traveler flange is provided with inner and outer portions which slope downwardly at their under sides and preferably lat substantially the same angle toward and merge into the body of the ring in substantially the same transverse plane. The traveler is thereby maintained substantially symmetrically positioned with respect to the axis of the ring and does not tend to swing in toward the bobbin thus causing yarn breakage. It will furthermore be observed that the traveler flange is of uniform structure throughout and consists of a single thickness of metal at both its inner and outer portions. From both theinner and the outer ed es of the traveler flange the said flange s opes downwardly to the upright or body portion of the ring. The thin, outer edge of said ring is, in the disclosed embodiment of the invention, in a horizontal plane substantially passing through the circumferential line of junction between the upright, inner edge of the traveler flange and t e said sloping portion extending downwardly therefrom. Thus the said thin outer edge of the traveler flange is below or substantiall below the thicker, upright, inner edge. '.he thin, outer edge 1s, however, outwardly directed, and the under side of the outer part of the flange extends smoothlv and without interruption from the outwardly directed, thin, outer edge of the flange to the body of the ring. This is an advantage, not only because it tends to preserve the symmetrical positioning of the traveler with respect to the axis of the ring, but also because it presents a surface that will cause the minimum amount of wear upon the outer terminal of the traveler and avoids the presentation of a downwardly directed, cutting angle or corner to the outer terminal of said traveler. The ring has a sharp or thin outer edge markedly Increasing in vertical thickness inwardly from said edge, and the top of the traveler flange slopes upwardly and inwardly to provide a friction-reducing inclined zone. Because of improved character traveler is'markedly reduced, and hence a higher speed can be obtained, `as well as an of yarn.

In the rotation of a traveler upon the flange ol' a spinning ring, -it intermittently` rises and falls, due probably to very slight variations in the tension of the yarn and perhaps also to other causes.. Such rising and falling action occurs also at the changes in direction of movement of the ring rail. This is a well known phenomenon. In such4 rise and fall, the under side of the outer portion of the traveler contacts intermittently Awith the outer part of the top of the ange of the spinning ring, and frequently to such an extent as to roughen said surface of the flange and even to raise a slight bur thereon. B removing the material, as herein describe flange, at the outer part thereof, I markedly reduce such contact of the traveler with the upper surface of said flange, and hence reduce the friction, and remove or very largely reduce the liability of roughening said surface of the flange.

It is common in mill practice to employ a tool in placing the traveler upon the flange of `a spinning ring. In this operation the traveler is strained, so that frequently it snaps or breaks and falls off after short use. With my improved ring it is unnecessary to employ a tool in placing the traveler upon the'ilange of the 'ring and hence the life o f the traveler is markedly prolonged. Furthermore, because of the sloping upper face of the race or flange, a larger air space is provided beneath the traveler, whereby the traveler is kept free of lint and lis kept cool and less liable to magnetize or burn ofl' when running at high speed. It is my belief that the thin outer edge of the ring assists in a rapid dissipation of heat` generated in the ring, incident to the spinning operation.

All spinners desire to employ, the heaviest travelers possible when spinning different numbers or counts' of yarn. I have found in the practice of my invention that I can employ heavier travelers than heretofore, thus winding the yarn more tightly, and permitting more yarn to be wound in a single package.

Having thus described one illustrative ernbodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.

' Claims:

1. A spinning ring provided with a traveler flange havlng a thin, outwardly directed, outer edge and an inner edge of greater vertical extent, the top of the flange throughout its major portion sloping downwardly from the upper surface of. the' to said outer edge, and the underside of the outer portion of 4said flange extending. directly to the body of the ring and presenting a smooth surface extending uninterruptedly from said outwardly directed, outer edge directly to and there merging into said ring body. l

2. .A spinning ring provided with a traveler flange, having a thin outwardly directed outer edge gle, circumferential line, the inner edge of the traveler flange being of markedly greater vertical extent than said outer edge, and the top of the said flange sloping downward from substantially the said inner edge to said outer thin edge, thereby markedly to reduce the contact in operation between the outer portion of the liange of the ring and said traveler.

3. A spinning ring having a body and traveler ange composed of -a single thickness of metal, said traveler flange being provided with an outwardly directed, thin outer edge that is of markedly less thicknessthan the body of the ring, the top of the flange throughout its major portion sloping downwardly to said outer edge, the under side of the outer portion of said iange extending directly to the body of the ring and presenting a smooth surface extending uninterruptedly from said outwardly directed, outer edge to said ring body and the inner edge presenting substantially -a sin-- of the said traveler flange being of mark.
